Factory reset problem on my broken iPhone 5s?

I broke my iPhone and the insurance company requires i factory reset the phone. Well i can't access that through the phone because the screen is completely shattered and shows nothing. So I backed up the phone through iTunes and try to restore it but it says it can't without the find my phone from iCloud being on so it needed me to turn it off. So I erased the whole account. Went back and it still says it is on even though iCloud says there's no devices on or connected.

I'm not sure. Contact a repairman.
